Agaricus bisporus – Page 22

Spent casing, Sphagnum moss, grass fibers, and green compost as peat alternatives in casing soils for Agaricus bisporus cultivation

mycolabadmin

Researchers tested alternative materials to replace peat in the soil layer used for growing button mushrooms. They found that moss and compost could replace up to 75% of peat without reducing mushroom yields, though grass-based materials were less effective. The study shows it is possible to move toward more sustainable mushroom farming while maintaining productivity and controlling plant diseases.

LC/MS- and GC/MS-based metabolomic profiling to determine changes in flavor quality and bioactive components of Phlebopus portentosus under low-temperature storage

mycolabadmin

This research examines what happens to black bolete mushrooms when stored in the refrigerator. Scientists used advanced chemical analysis to track how the mushroom’s flavor and nutritional compounds change over a two-week period. They discovered that an earthy smell compound called geosmin builds up during storage, which affects how the mushroom tastes. The findings suggest that cold storage alone is not ideal, and better preservation methods need to be developed.

Elucidation of Mechanism of Soil Degradation Caused by Continuous Cropping of Dictyophora rubrovalvata Using Metagenomic and Metabolomic Technologies

mycolabadmin

When farmers grow Dictyophora rubrovalvata mushrooms in the same soil repeatedly, the soil becomes degraded and mushroom production fails. Scientists found that repeated cultivation changes the soil’s microbe populations, reducing beneficial bacteria while increasing harmful fungi, and toxic compounds accumulate that further damage mushroom growth. By understanding these mechanisms through DNA sequencing and chemical analysis, better strategies can be developed to maintain healthy soil for sustainable mushroom farming.

New insights into temperature-impacted mycovirus-fungus interactions regulated by a microRNA in Lentinula edodes

mycolabadmin

When shiitake mushrooms are infected with a virus and exposed to heat stress, the virus replicates more aggressively, which makes the mushrooms more susceptible to heat damage and competitive fungi. Researchers discovered that a small regulatory RNA molecule called led-milR-21 plays a key role in this process by suppressing the mushroom’s heat defense mechanisms when the virus is present. This discovery is important because it shows how viruses can exploit heat stress to overcome fungal defenses, with implications for mushroom cultivation in a warming climate.

Whole Genome Sequence of an Edible Mushroom Stropharia rugosoannulata (Daqiugaigu)

Scientists have decoded the complete genetic blueprint of the wine cap mushroom (Stropharia rugosoannulata), a popular edible mushroom grown worldwide. The research identified over 12,000 genes and discovered the mushroom contains powerful enzymes that break down plant material, explaining why it grows so well on straw and corn stalks. The study also revealed that different parts of the mushroom (cap and stem) have different functions, with stems focusing on energy production and caps on growth and development.

Genome Sequencing of Cladobotryum protrusum Provides Insights into the Evolution and Pathogenic Mechanisms of the Cobweb Disease Pathogen on Cultivated Mushroom

mycolabadmin

Researchers sequenced the complete genome of Cladobotryum protrusum, a fungus that causes cobweb disease on cultivated mushrooms. This genome contains genes for producing toxins and enzymes that help the fungus attack and digest mushroom cells. Understanding this genetic blueprint could help farmers develop better strategies to control this disease and protect their mushroom crops from significant economic losses.

Impact of bottom ash addition on Pleurotus ostreatus cultivation on coffee ground substrate

mycolabadmin

This study investigated growing oyster mushrooms on a mixture of used coffee grounds and coal plant bottom ash. The researchers found that adding small amounts of bottom ash (1-5%) slowed mushroom growth slightly but actually reduced harmful heavy metals in the final mushrooms compared to using only coffee grounds. The leftover substrate after mushroom harvest could be used as a fertilizer for poor soils, creating a complete recycling system that turns industrial and food waste into useful products.

Transcriptome Analysis Reveals Critical Genes Involved in the Response of Stropharia rugosoannulata to High Temperature and Drought Stress

mycolabadmin

This study examined how a type of edible mushroom called Stropharia rugosoannulata responds to high heat and dry conditions by analyzing which genes become active. Researchers found that under stress, the mushroom activates specific genes that help it survive, particularly through a cellular communication pathway called MAPK. They identified 15 key genes that could be useful for breeding mushroom varieties that better withstand harsh growing conditions, which could improve mushroom farming efficiency.

The Fungus Among Us: Innovations and Applications of Mycelium-Based Composites

mycolabadmin

Mycelium-based composites are eco-friendly building materials made by growing mushroom fungus on agricultural waste like sawdust and straw. These materials are lightweight, provide excellent insulation and soundproofing, and are much more sustainable than synthetic alternatives. However, they absorb water easily and aren’t strong enough for load-bearing structures, making them best suited for insulation and non-structural panels.

Research on an Improved Segmentation Recognition Algorithm of Overlapping Agaricus bisporus

mycolabadmin

Scientists developed a new computer vision system that can automatically identify and locate overlapping button mushrooms (Agaricus bisporus) in factory farms. The system uses image processing techniques to overcome challenges like uneven lighting and crowded mushrooms. It successfully identified mushrooms with over 96% accuracy, which could help automate the mushroom harvesting process and reduce labor costs for farmers.
